Gibibytes to tebibytes (GiB to TiB)

To convert gibibytes to tebibytes (GiB to TiB): one gibibyte is 0.0009765625 tebibytes, so 1,000 GiB is 0.976563 TiB.

Swap units: TiB to GiB

In tebibytes0.976563 TiB

Conversion factor Exact by definition: the decimal prefixes (kB, MB, GB, TB) step by exactly 1,000 and the binary ones (KiB, MiB, GiB, TiB) by exactly 1,024.
1 gibibyte = 0.0009765625 tebibytes
The other way
1 tebibyte = 1,024 gibibytes
Working
1,000 x 0.0009765625 = 0.976563

Decimal vs binary prefixes Drive manufacturers use the decimal GB and operating systems traditionally reported the binary one, which is why a 1 TB drive shows as 931 GB. Both numbers are correct; they are different units.

How the Unit Converter works

One gibibyte is exactly 0.0009765625 tebibytes. That is the definition of the prefixes, not a measurement: the decimal SI prefixes (kilo, mega, giga, tera) step by exactly 1,000, and the binary IEC prefixes (kibi, mebi, gibi, tebi) step by exactly 1,024. The two families are both exact; the trouble is only that software and storage labels do not always say which one they mean.

Worked through: 1,000 GiB x 0.0009765625 = 0.976563 TiB.

Going the other way, one tebibyte is 1,024 gibibytes.

For mental arithmetic: Divide by 1,024. 512 GiB is half a TiB.

1,024 GiB to the TiB, exactly. This is the conversion for storage quotas and volume sizes set in GiB that add up to something worth stating in TiB: a 500 GiB volume is 0.488 TiB, and 2,048 GiB is exactly 2 TiB. It differs from GB to TB, which divides by 1,000, by 2.4% at this step, so a total computed in one system and compared with a limit in the other will look slightly over or under.

Precision is worth matching to the input. A measurement given as 100 GiB carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.

Unit Converter FAQ

How many tebibytes are in a gibibyte?

0.0009765625. That is exact by definition: the prefixes step by exactly 1,000 (SI) or 1,024 (IEC).

What is 1,000 GiB in tebibytes?

0.976563 TiB. Multiply by 0.0009765625: 1,000 GiB x 0.0009765625 = 0.976563 TiB.

How do I convert tebibytes back to gibibytes?

Divide by 0.0009765625, or equivalently multiply by 1,024. One tebibyte is 1,024 gibibytes. The two factors are reciprocals, so you only need to remember one of them.

Is there a quick way to do this in my head?

Divide by 1,024. 512 GiB is half a TiB. It is close enough for everyday use.
